Shielded wire pressing mechanism for capacitive touch screen

Abstract

The invention discloses a shielded wire pressing mechanism for a capacitive touch screen, which comprises a base, wherein an interlayer is arranged on the base; a heating device is arranged in the interlayer; a first baffle block and a second baffle block are arranged on the upper surface of the base; a pressing device is arranged at one end of the base close to the second baffle block; the pressing device is parallel to the first baffle block; the pressing device comprises a supporting base which is fixedly connected with the base; an axle hole is formed on the supporting base; a rotating shaft is rotatably arranged in the axle hole; and a pressing block is connected with one end of the rotating shaft. The shielded wire pressing mechanism for the capacitive touch screen has a simple structure and is easy to realize; the pressing block having an arc-shaped structure on the shielded wire pressing mechanism is driven to rotate by the rotating shaft, so as to realize the pressing of the shielded wire; the operation is convenient; the labor intensity is reduced; the production efficiency is increased; and the shielded wire pressing mechanism is used for effectively solving the problems that the tilt pressing is easily caused and the defective rate of products is high if the shielded wire pressing is manually finished and the fingers are easy to pain after the fingers of workers perform the pressing operation for a long time.

Description

technical field [0001] The invention relates to a pressing mechanism, in particular to a shielding wire pressing mechanism of a capacitive touch screen widely used in the touch screen industry. Background technique [0002] The capacitive touch screen is to paste a layer of transparent special metal conductive substance on the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch position can be determined to obtain information. The existing capacitive touch screens are equipped with shielding wires to prevent interference during the working process of the capacitive touch screen; the shielding wire of the capacitive touch screen is to paste a layer of anisotropic conductive film on the sensor body, and then carry out pre-pressure and local pressure. However, the shielding wires of the existing capacitive touch screens a...
